A South Tyneside man has been charged with threatening to kill after allegedly posting on Facebook he would kill 200 Americans.
Reece Elliott, 24, from South Shields, has also been charged with making malicious communications, Northumbria Police said.
According to reports, the post was made anonymously on an online memorial page, set up for a Tennessee student who died in October.
That led schools in Warren County, Tennessee, to tighten security, with limited access to premises.
